Calendar Creator Deluxe v 12.1

I encountered the same problem, and I could also not uninstall the program for the same reason.  I found that if you disable the UAC via Regedit program, it will work.  I hate to pay Broderband $30 for the same program again (for a .1 upgrade?  That's Unconscionable!).  I use it so infrequently that I will just turn UAC off and back on when I do.  Here's the path to use in REGEDIT program:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

then click on the EnableLUA item,  and then change the Value  "1" entry to a Zero, and back again as needed.

I reported the problem to Broderbund.  They said there is code in Version 12.1 that is not compatible with the updated Windows 10.  Their suggestion was to update to Version 12.2.

I purchased this Version for $29.95 but used the code WELCOME25 for a 25% discount . Download and installed the new version. 

CC retained my settings from the previous version and works well

Program stopped running today... Administrator has Blocked.  My login is as Administrator. After many attempts to resolve. I backed up my files and uninstalled.  I now get to same block message for the Setup program when I try to reinstall.  Any suggestions?

I have the same problem.  I am the only user on my privately owned computer and the only person who has administrator access.  Suspect it is a problem with the recent windows update.  I bought the program, have used it for years and want to continue using it.

Ver 12.2 has the exact look and feel of my old Ver 12.1
